Answer:

$26.25

Step-by-step explanation:

I'm not completely sure if I did this right because I haven't used this in a while, but let's say sodas are x and hot dogs are y. The first equation would be  3x+4y=15 and in order to solve for x or y you have isolate them to seperate sides because if there is not letter on the other side, it will just end up being zero... if that makes sense. subtract 3x so the equation is now 4y=15-3x and divide everything by 4, to make the equation y=3.75-3/4x. Do the same thing but subracting the 4y and dividing by 3 to get the x value. Now we're left with y=-3/4+3.75 and x=5-4/3y (or x=5-1 1/3y). remember that x=sodas and y=hotdogs. The equation we need to create has seven hot dogs and no sodas, so we simply need to take the equation for y and substitute y for 7 because we have 7 hot dogs and y is the symbol used for hot dogs. This equation would now be 7(-3/4x+3.75) because hotdog=y=-3/4x+3.75, so hotdog=-3/4+3.75 and we have 7 hot dogs so you just multiply that by 7

Step-by-step explanation:

6m+15n-12p/n where m=-3.5, n=4 and p=3

6(-3.5)+15(4)-12(3)/4=-21+60-36/4

-21+60-9=-30+60=30

Answer:

y is 40

x is 16

(a) The value of 9 + (1/2) /4 * 48

We have:

[tex]9 + (1/2) /4 * 48[/tex]

Evaluate the quotients

[tex]9 + (1/2) /4 * 48 = 9 + 1/8 * 48[/tex]

Evaluate the products

[tex]9 + (1/2) /4 * 48 = 9 + 6[/tex]

[tex]9 + (1/2) /4 * 48 = 15[/tex]

Hence, the value of the expression 9 + (1/2) /4 * 48 is 15

(b) If x = 2.7, 5x =

The value of x is given as 2.7.

So, we have:

[tex]5x = 5 * 2.7[/tex]

[tex]5x = 13.5[/tex]

Hence, the value of 5x is 13.5

(c) Equivalent expression of 12x - 8x + 3

The expression is given as: 12x - 8x + 3

So, we have:

12x - 8x + 3 = 4x + 3

Hence, the equivalent expression of 12x - 8x + 3 is 4x + 3

(d) Equivalent expression of 3(x + 3y + 2x - y)

The expression is given as: 3(x + 3y + 2x - y)

So, we have:

3(x + 3y + 2x - y) = 3(3x + 2y)

Also, we have:

3(x + 3y + 2x - y) = 9x + 6y

Hence, the equivalent expressions are 3(3x + 2y) and 9x + 6y

(e) The value of 1/2x^3 + 5.2y when x = 2 and y = 3

We have: 1/2x^3 + 5.2y

So, the expression becomes

[tex]1/2x^3 + 5.2y = 1/2 * 2^3 + 5.2 * 3[/tex]

[tex]1/2x^3 + 5.2y = 19.6[/tex]

Hence, the value of 1/2x^3 + 5.2y is 19.6

(f) The commutative property of addition of 8 + 3m

The commutative property of addition of 8 + 3m is 3m + 8

(g) The algebraic expression for "5 times the sum of 2 and y?

The algebraic expression is 5(2 + y)

(h) The error of the student

The student's first error is in step 2: 4(2) + 4x(2)

(i) The statement that describes the expression 3 + y ÷ 2

The correct statement is (d) the sum of 3 and the quotient of y and 2

(j) The value of an expression

We have:

22 + 62 ÷ 22

Evaluate

22 + 62 ÷ 22 = 24.8

Hence, the value of the expression 22 + 62 ÷ 22 is 24.8

(k) Complete the blanks

We have: 34 + 2 ⋅ 5 = ____

Represent the blank with x

34 + 2 ⋅ 5 = x

Evaluate

44 = x

Hence, the blank is 44

(l) The algebraic property is used to rewrite 2(4y + 1) as (4y + 1)(2)?

The algebraic property is used to rewrite 2(4y + 1) as (4y + 1)(2) is the  (c) commutative property of multiplication

(m) The statement that best describes the expression 4y ÷ 9

The statement is: (c) 4 times y divided by 9

(n) The expression is equal to 5p

The expression is equal to 5p is (a) p + p + p + p + p

(o) The coefficient of y in the expression 2 ⋅ 4 + 3y

The coefficient of y in the expression is 3

The Volume of Pizza box is 686 inches³.

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

Given:

We have pizza box of shape Cuboid

length = 14 inches

width = 14 inches

height= 3.5 inches

So, Volume of box

Answer: B. G(x)=3f(x)

Step-by-step explanation: hope this helped :)

The equation that represents the graph of the function g(x) is g(x) = 3f(x)

The equation of the function f(x) is given as:

f(x) = x^2

The function g(x) is compressed horizontally by a factor of 3, to get the function g(x)

This means that:

g(x) = kf(x)

Where k = 3.

So, we have:

g(x) = 3f(x)

Hence, the equation that represents the function g(x) is g(x) = 3f(x)

Use the formula,

I = Prt

P = Principal amount = 400

I = interest = 18

r = annual rate

t = time in years = 9/12 = 3/4

so,

18 = 400*r*3/4

r = 0.06

so the annual interest rate is 0.06 or 6%

Answer:

Step-by-step explanation:

principal 800 multiply by 3.5 percent

2800 is the interest multiplied by 6 months

=16800/ 168.00

Based on the information given the interest earned is $14.

Using this formula

Interest=Principal ×Rate × Time

Where:

Principal=$800

Rate=3.5% or 0.035

Time=6/12

The Circumferance of the circle would be 22 inches.

A circle is a locus of a point whose distance always remains constant from a given specific point. The general equation is -

x² + y² = r²     (for circle centered at origin)

Given is a circle that has a diameter of 7 inches,

We have -

Diameter [d] = 7 inches

Then, radius [r] = 7/2 = 3.5 inches.

Circumferance = 2 x 22/7 x 3.5 = 22 inches

Therefore, the Circumferance of the circle would be 22 inches.

The number of containers to put all the fertilizers in is 4 containers.

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example:

1/2, 1/3 is a fraction.

2/4 x 5/6 = 10/24 = 5 / 12 is a fraction

5/6 ÷ 1/3 = 5/6 x 3/1 = 5x3 / 6x1 = 15/6 = 5/2 is a fraction.

We have,

Amount of fertilizer = 4/5 pounds

Amount in each container = 1/5 pounds

The formula to divide fractions is

a/b ÷ c/d

a/b x d/c

ad / bc

The number of containers to put all the fertilizers.
